Toboggan Creek Coho Smolt Enumeration 1997
Juvenile coho were sampled in Toboggan Creek using a fyke trap, for the third consecutive year. Weekly sampling of coho was conducted over two to three sampling periods (3 - 25 hours in length) between May 7 and June 29, 1997. A total of 1628 wild coho and 1276 hatchery coho were caught in the fyke trap in the spring of 1997. Trap performance was generally good, and it is felt that catches were a direct indicator of effort and migration rates. The peak of migration of coho smolts appeared to occur between May 28 and June 24, 1997. Increased water levels and changes in trap design appeared to increase mortality, and resulted in lowered sampling intensity towards the end of the study.
